FINISHING-MOLD FOR MAKING GLASS BOTTLES.

SPECIFICATION forming part of Letters Patent No. 691,463, dated January21, 1902.

Application filed May 25, 1901.

To all whom, it Wtcty concern.-

Be it known that I, LUDWIG GRoTE, a subject of the Emperor of Germany,residing at 84 East India Dock road, Poplar, London, England, haveinvented a new and useful Improvement in Finishing Holds for MakingGlass Bottles,of which the following is a specification.

This invention relates to finishing body and bottom molds for use in theart of making glass bottles and primarily to such molds for use inconnection with but detached from machines for making bottlessuch, forexample, as either of the machines set forth in my previousspecifications forming parts of United States Letters Patent No.628,313, dated the 4th day of July, 1899, and No. 656,286, dated the21st day of August, 1900. In such machines the molten glass for eachbottle is measured, the head is cast, the interior of the neck isformed, and the blowing is begun Within neck and parison molds form- Theparison is then inclosed within a finishing-mold and the blowingcompleted, whereby the body and bottom of the bottle are given theirfinal shape and dimensions.

For the purposes of the present invention the head of the bottle may beformed and the measuring and blowing operations may be performed in anyknown or improved manner.

The objects of this invention are to facilitate quickly and tightlyclosing the joints of the mold and by the same means to facilitatethrowing open the mold to free the finished bottle preparatory to itsremoval from the mold.

The invention consists in an improved finishing body and bottom mold andin certain novel combinations of parts therein, as set forth in thefollowing description, and pointed out in the appended claims.

Two sheets of drawings accompany this specification as part thereof.

Figure 1 is a front elevation of the improved finishing-mold open. Fig.2 is a like view of the same closed. Fig. 3 is an elevation of theclosed mold from one of its hinge sides. Fig.

4 is a plan view projected from Fig. 3. Fig.

Serial No. 61,908. (NomodeL) 5 isa plan View of the bottom-molding partdetached, and Figs. 6 and 7 are respectively a vertical section and aplan view of the base of the improved mold detached.

Like letters and numbers refer to like parts in all the figures.

The body-molding portion of the improved finishing-mold'is bisectedlongitudinally, and its halves A and B swing together and apart, as iscustomary, on hinges 1 and 2, the axes of which are parallel to theplane of the 1ongitudinal joints between said halves or body parts. Thebody parts A and B are thus hinged to a vertically-movablebottom-molding part O, Fig. 5, hereinafter termed the bottom part,beneath which is a base D, Figs. 6 and 7.

The body parts A and B are constructed, as is customary, with mid-heightlugs 3 and 4 at one side of the mold, herein termed its front, andhandlesaandbare respectively rigidly attached to said lug 3 andpivotally attached to said lug 4, the latter by a locking-bolt 0, havinganon-circular head which passes through a hole d, Fig. 3, of like shapein said lug 3, and is interlocked with the latter when the mold isclosed by swinging the handle 17 into the positionin which itis shown inFigs. 2 and 3.

The body parts A and B are further constructed with lugs e and f, Fig.4, which coact with diametric lugs g and h, Fig. 5, on the bottom part 0and with pintles q; and j, Fig. 4, to form the hinges l and 2, said lugsg and h on the bottom part being preferably and conveniently providedwith the customary stops 5 and 6, Figs. 1 to 5, against which the bodyparts rest when the mold is open, as in Fig. 1, as means for limitingthe separation of said body parts.

The hinges l and 2 are necessarily loosejointed, so as not to beaffected by the changes of temperature of the mold and so that the mold,whether hot or cold, may be quickly opened and closed. Such looseness ofthe hinges militates against adapting the body parts to properly cometogether along their longitudinal joints, especially at the back of themold, (shown at the left in Figs. 3 and 4,)

which is opposite the handles a andb, that have heretofore been reliedon for this purpose.

To assist in bringing the body parts A and B tightly together when themold is closed and at the same time tightly closing the joint betweensaid body part and the bottom part 0, the latter is made verticallymovable, as aforesaid, and is constructed with vertical holes 7 and 8,Fig. 5, surroundingits matrical surface 9, Fig. 5. The base D isprovided at top with tapped sockets 10, Figs. 6 and 7. Guide-pins k,Figs. 1, 2, and 3, are screwed fast in said sockets 10 and looselyfitted to said holes 7 and pins Z, somewhat longer than the protrudingportions of the pins 70, rest loosely upon the base D and are looselyfitted to said holes 8 of the bottom part C.

The pins and Z are arranged to contact with the lower ends of the bodyparts A and B when the mold is closed, and their upper ends are roundedand project above the bottom part in the open mold with reference tosuch contact.

When the open mold, Fig. 1, is closed upon a parison by means of. thehandles a and b, the body parts A and B first move freely toward eachother on the axes of the hinges 1 and 2 and describe by their upperangles the arcs m, Fig. 1. The lower ends of said body parts thus comein contact with the projecting upper ends of the pins 70 and Z, firstwith the pins 70 nearest the axes of the hinges, so as to obtain thegreatest leverage in overcoming the inertia of the bottom part 0 and itsload, and then with the higher upper ends of the pins Z in contact withwhich the body parts lift the bottom part until all the joints of themold are tightly closed, as in Fig. 2. The compound movement of saidupper angles of the body parts after the contact of the latter with thepins is represented by the arcs 'n, Fig. 1.

The mold is fastened in its closed condition by means of the handle I),as aforesaid. Then it is unfastened, the weight of the bottom part 0 andits load assists in quickly opening the mold until the body parts A andB rest against the stops 5 and 6 and the bottompart upon the top of thebase D again, as in Fig. 1.

The-separation of the bottom part 0 and base D may be limited by anysuitable meansas, for example, by one or more vertical screwbolts 0,Figs. 1 and 2, having countersunk upper ends which occupy holes 11, Fig.5, in the bottom part 0, and lower ends extending through holes 12,Figs. 6 and 7, in the top of the base D, and provided with nuts p, Figs.1 and 2, to contact with the top of the chamber within the base, as inFig. 2.

The external as Well as the internal shape of the mold,and particularlythose of the base D, may be widely varied at will, the pins 7.: and Zmay be increased or reduced in number, and different means for fasteningthe mold may be used. Other like modifications will suggest themselvesto those skilled in the art.

Having thus described said improvement, I claim as my invention, anddesire to patent under this specification 1.
